I've found TP issues to be manageable at 785 SS. That said, here is the Gear Set I will be using 723 Acc, 934 Crit, 599 Det, 690 SS After experiencing A5s and A6s, I do not think worrying about SS as long as its under 800 should be too much of an issue.

Overall it takes 18 V materia. On my server that would run about 9~15M, but I have like 4-500 Diadem Spoils and some airships at my disposal. I know the materia will be impossible to get for some peeps, I suggest you try and make diadem a thing again. My suggestion, we bring back Tri-Island farms on Hard Mode. You can get enough for 1-2 Materia per person a run there if your group is good enough, and as long as there are 5 or so groups there (Thats how I got my 4-500 or so in the two weeks Diadem was actually relevant).
